Answer:
Three sources of natural fibers include: animals, plants, and minerals
Animal fibers are composed of proteins that come from an animal's hair, fur, or webbing.
Plant fibers are a specialized type of plant cell. Different types of plants have a wider range of physical and chemical characteristics. Cellulose has a strong resistance to many chemicals and won't dissolve in water.
A number of fibers exist that are derived from natural mineral sources or are manufactured from inorganic and mineral salts. These fibers are predominantly derivatives of silica (Si02) or other metal oxides.
A series of man-made inorganic fibers other than glass exist that are nonflammable, heat-stable amorphous materials useful in industrial fabric constructions, including refractory materials. These inorganic fibers include pure silica, potassium titanates, aluminum borosilicates, and aluminum oxide-zirconium oxide polymers, Most of these fibers have high strength, are less susceptible to chemical attack than glass, and melt above 1000°.
